SPRING-BEARING FOR WHEELBARROWS.

SPECIFICATION formi-ng part of Letters Patent No. 427,655, dated May 13,1890.

Application filed January 6, 1890. Serial No.336,058. (No model.)

To all whom t may concern:

Be it known that'I, DANIEL J. C. ARNOLD, a citizen of the United States,and a resident of New London, county of Huron, and State of Ohio, haveinvent-ed certain new and use ful Improvements in Spring Bearings forVheelbari-ows; and I hereby declare the following to be a clear, full,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to spring-bearings for hand-barrows, and itsobjects are to relieve the shock occasioned to the hand whenencountering an obstacle in the path of the barrow and to provide asimple, durable, and inexpensive spring-bearing adapted to heavy loads.f

Heretofore the axle-bearin gs for brick-barrows have been mounted uponthe :t'ree rear extremities of leaf-springs lying underneath the siderails and extending longitudinally with them and fastened to them attheir forward ends by bolts or otherwise. A disadvantage arose from thisusage in the shock occasioned the hand in wheeling the barrow when anobstacle was encountered, the spring merely transferring the shockwithout modifyin it.

My invention consists in the employment of a sprin havin semi-ellipticalor rounded form at the forward end of the rail, the upper and shorterarm being fastened to the rail, while the longer arm extends rearwardtoward ihe handles. On this end the bearings are placed, having freevertical movement.

In the accompanying drawings the construction of the limproved springand its appearance are clearly shown.

Figure l is a perspective view of a barrow provided with the spring, andFig. 2 a detail of one of the springs.

A is a barrow; B B, the springs secured with bolts, as ZJ Z), to therails D. Guides E are employed tokeep the movement of the springsvertical, and the axlebearings F are secured, as usual, by bolts f tothe free ends of the spring.

It will at once be seen that any shock sustained by the forward movementof the wheel will be arrested and reduced in force by the vibration ofthe spring B, from its peculiar position, and relieve the hand from itsforce.

I am aware that springs have been employed to prevent the transmissionof the shock to the hand from the wheel, which, however, have beencomparatively flat multiple springs pivoted instead ot rigid at theforward end and with the rear extremity pressing against the rail, whichgives butlittle range of movement or elasticity to the spring and novertical movement to the free end.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In a hand-barrow, springs supporting the wheel-axle, rigidly securedto the hand-rails at their forward ends, but having their rearwardextremities free to move vertically, and provided with bearings for thewheel-axle, substantially as and in the manner set forth.

2. In a hand-barrow, springs to support the wheel-axle and receive theshocks upon the wheel, consisting of single strips secured to the outerends of the hand-rails and thence extending toward the rear, with rearends free to move vertically in vertical guides, all substantially asdescribed.

3. In a hand-barrow, springs Qsecu red to theV outer ends of the bottomrails at their outer extremities, but having free vertical move-- mentat their inner extremities, in combination with bearings for thewheel-axle, and vertical guides, substantially as described.

4. In a hand-barrow, spring-strips bentinto loops with parallel sides,one longer than the other, the shorter arms being secured to the outerends of the hand-rails, while the inner ends are free to move verticallytoward the rail,as and in the manner specied.

In a hand-barrow, spring-strips bent into loops with parallel sides, oneside longer than the other, the shorter sides being secured to the outerends ot' the hand-rails, while the inner ends are free to movevertically toward the rail in guides, all substantially as and in themanner specified.
